Mi Choripan proudly serves up "Argentinian Soul Food" - aka overstuffed chorizo-sausage sandwiches seasoned with chimichurri sauce, which are sold from street stalls in Argentina and other parts of Latin America, and now in Tokyo. Sausages are grilled to order while you wait, and while they're quite good on their own, we'd recommend springing for an extra Y300 to liven up your sandwich with the shop's selection of optional toppings.

This book will introduce you to more than twenty of Japan's favorite specialty foods that are less well known abroad, along with a guide to the best places in Tokyo to try them and expert tips on what to order. From Bento.com.
